     3== Background Information ==
     4 
     5The GEMINI instrumentation and measurement services must be applied
     6to an existing slice.  This tutorial assumes the reader is familiar
     7with the process of creating slices, and we do not describe the steps
     8needed to create a slice in this tutorial.  However, in this tutorial
     9we will be using a particular example topology.  We also assume the
     10user will access the topology using the user workspace VM designed
     11specifically for this tutorial.  The example topology RSPEC and the
     12instructions for accessing the slice using the user workspace are
     13given here a background information.

     18== Instrumentation ==
     19
     20After a slice has been created, we are ready to begin installing the GEMINI tools and
     21services into that slice.  We call this the "instrumentation" step.  This step can take
     22a significant amount of time.  Depending on the size of your topology, this can take minutes
     23to hours.  To avoid wasting time waiting for the tutorial slice to instrumentize, we have
     24already created a set of example of slices and instrumentized them, so there is no need to
     25instrumentize your slice in this tutorial.  However, the process of instrumentizing a slice
     26with the GEMINI tools is given on the [wiki:GEMINI/Tutorial/GEC15/Background/Instrumentize GEMINI Instrumentize] web page.

     28== Running the Experiment ==
     29
     30Before we can use the GEMINI tools to monitor an experiment, we must initiate the experiment.
     31In particular, we will want to generate traffic that can be measured by GEMINI.  For the purposes
     32of this tutorial, we implemented a simple GUI that makes it easy to generate traffic in our
     33experimental topology.  To access and use the GUI, please follow the instructions
     34given on the [wiki:PathControllerDemo] Experiment Controller Web Page].
